问题描述

我试图写一个Excel文件，但是我不断收到错误：

  

异常线程mainorg.apache.poi.POIXMLException：org.apache.poi.openxml4j.exceptions.InvalidFormatException：包装应包含的内容类型的一部分​​[M1.13]

解决方案

检查Excel格式....首先，我创建了一个样本与POI擅长，我改变了列与我首先尝试给它同样的错误，但很少尝试后，成功读取。我不知道为什么它没有工作第一次运行:(
但如果你有正确的库，请检查正确的Excel格式

I am attempting to write to an Excel file however I keep getting the error:

Exception in thread "main" org.apache.poi.POIXMLException: org.apache.poi.openxml4j.exceptions.InvalidFormatException: Package should contain a content type part [M1.13]

From what I understand I am missing a jar file.

Can anyone help me identify which file it is?

P.S. I am using Netbeans.

import java.io.FileNotFoundException;
import java.io.FileOutputStream;

import org.apache.poi.xssf.usermodel.XSSFWorkbook;

        XSSFWorkbook wb;
        XSSFCell r1c1, r1c2, r1c8, r1Episodes;

        FileInputStream fis = new FileInputStream("/Users/nicholaskissaun/Google Drive/Grade 11_12/Computer Science/Java/Term1/src/IA/Profiles/Becky/ShowDetails.xlsx");           
        wb = new XSSFWorkbook(fis);  
        s = wb.getSheetAt(0);
